To help define "unless you're nearby"...
I have played numerous times with other hams on 900 MHz. We find 15 or 30 watt mobile-to-mobile distance (simplex) is usually less than ONE mile. And if either side is using an HT, that distance could easily go down to 2-5 city blocks! Even with a five watt HT. 800 and 900 MHz signals go through buildings and other obstacles great, but they quickly run out of steam further from their transmit antenna.
So if SSPD uses tactical talk around, you need to be well within a mile of their location to even hear them. Maybe even a couple city blocks.
